Mhoro, huya kuzobvunza zvigadzirwa zvedu!
Steel space grid gas station project construction

Iyi purojekiti ndeye square space frame / kureba 16 metres / yakazara kureba 30 metres / yakazara span 18 metres

1. Kuiswa kwesimbi nzvimbo yesimbi kunofanira kuitwa mushure mekugamuchirwa kweiyo yakadzika dhizaini axis uye yakamisikidzwa bhodhi.Zvinodiwa zverutsigiro rwepasi ndezvi: mutsauko wehurefu pakati pezvitsigiro zviri pedyo (kure L2): kukosha kuduku kweL2 / 800 uye 10mm, pakukwirira kwakafanana Urefu musiyano pakati pepamusoro uye pasi pasi rutsigiro: 20mm;

2. Sarudza nzira yekugadzika kwesimbi nzvimbo yesimbi maererano nemasimba uye maitiro ehutano hwegridhi uye mamiriro chaiwo ekuvaka panzvimbo;

3. Mushure mekuiswa kwesimbi nzvimbo, inofanirwa kuongororwa:

a.Iko kukosha kunotenderwa kwekutsauka uye kwakachinjika kwedivi kureba kwe1/2000 yehurefu, uye haifanire kunge yakakura kupfuura 30mm;

b.Iko kukosha kunobvumirwa kwepakati pekugadzirisa kunofanira kuva 1/3000 yepakati penzvimbo yesimbi, uye haifaniri kunge yakakura kudarika 30mm;

c.Kune mesh furemu inotsigirwa neinotenderera, kureba kunotenderwa kutsauka i1/400 yerutsigiro rwepedyo, uye haifanire kunge yakakura kupfuura 15mm, uye iyo yakanyanya uye shoma haifanire kunge yakakura kupfuura 30mm;kune mesh furemu inotsigirwa nemapoinzi akawanda, iyo inotenderwa kureba kutsauka i1/800 yerutsigiro rwepedyo, uye haifanirwe kunge yakakura kupfuura 30mm;

d.Ziva kutsauswa kwegridi zvinoenderana nezvinodiwa uye dhizaini zvinodiwa.Mushure mekuvaka, kutsauswa kwesimbi space frame hakuzove kwakakura kupfuura 115% yehuwandu hwekuverenga kukosha.(Yakanyanya kutsauka kukosha kwegridi furemu L/250)

4. Kana pane mabhora ekuputika munzvimbo, groove welding inoshandiswa kusungira bhora rekutsvaira uye tsvimbo, uye giredhi rekushongedza seam haifaniri kunge yakaderera kupfuura yechipiri.

5. Mushure mekuiswa kwesimbi nzvimbo yesimbi yakapedzwa, pamusoro pemajoini emuchadenga nematanda anofanira kunge akachena uye asina mavanga uye tsvina.Majoini nemakomba akawandisa ebhoti bhora majoini anofanira kuzadzwa uye kuvharwa negirisi.

6. Panguva yekushandiswa kwegridi, kuchengetedzwa kwakakwana kwekudzivirira-corrosion kunofanira kuitwa makore ose mana kusvika ku5.

 

1. The installation of the grid frame must be carried out after the acceptance of the lower structure axis and the embedded board. The requirements for the lower support are: the height difference between adjacent supports (distance L2): the smaller value of L2/800 and 10mm, at the same elevation Height difference between the highest and lowest support: 20mm; 2. Determine the installation process of the grid according to the force and structural characteristics of the grid and the actual construction conditions on site; 3. After the grid frame is installed, it should be checked: a. The allowable value of the vertical and horizontal side length deviation is 1/2000 of the length, and should not be greater than 30mm; b. The allowable value of center offset should be 1/3000 of the span of the grid, and should not be greater than 30mm; c. For the mesh frame supported by the periphery, the allowable height deviation is 1/400 of the adjacent support, and should not be greater than 15mm, and the maximum and minimum should not be greater than 30mm; for the mesh frame supported by multiple points, the allowable height deviation is 1/800 of the adjacent support, and should not be greater than 30mm; d. Detect the deflection of the grid according to the specifications and design requirements. After construction, the deflection of the grid frame shall not be greater than 115% of the design calculation value. (Maximum deflection value of grid frame L/250) 4. If there are welding balls locally, groove welding is used for welding the welding ball and the rod, and the welding seam grade should not be lower than the second grade. 5. After the installation of the grid frame is completed, the surface of the joints and rods should be clean and free of scars and dirt. The joints and excess holes of the bolt ball joints should be filled and sealed with grease. 6. During the use of the grid, comprehensive anti-corrosion maintenance should be carried out every 4 to 5 years.
